根据条件合并两个查询结果

Question

I have two query results.I need to merge the query result based on a condition.

$portfolio = DB::table('architects_portfolio')->get();

 $img=DB::table('architects_portfolio_images')
          ->distinct()->get(['architects_images_id']);

and my condition to merge is

architects_portfolio.id = architects_portfolio_images.architects_images_id

I have my first table 'architects_portfolio' which contain portfolio and second table 'architects_portfolio_images' which contain images of portfolio.I need to get only one image for now.But I get all images of portfolio now by using below code.But I need only one

 $architect = User::find($user_id)->architect;               
 $portfolio = ArchitectsPortfolio::join('architects_portfolio_images as images', 'architects_portfolio.id', '=', 'images.architects_images_id')
            ->where('architects_portfolio.architects_id', $architect->id)
            ->select('architects_portfolio.id', 'architects_portfolio.architects_id', 'architects_portfolio.name', 'architects_portfolio.description', 'images.filename','images.architects_images_id')
            ->distinct()->get(['images.architects_images_id']);

My tables architects_potfolio

architects_portfolio_images

Answer 1

 $querys = DB::table('architects_portfolio');    
 $querys->select('architects_portfolio_images.architects_images_id');
 $querys->join('architects_portfolio','architects_portfolio.id','=','architects_portfolio_images.architects_images_id')->distinct()->get();

You should try this:

$rsltArchitectDetails = DB::table('architects_portfolio')
                    ->select('architects_portfolio_images.architects_images_id')
                    ->join('architects_portfolio_images', 'architects_portfolio.id' , '=', 'architects_portfolio_images.architects_images_id')
                    ->distinct()
                    ->get();

Answer 3

The best way is to use relationships , then you could just load portfolios with related images:

$portfolios = ArhitectPortfolio::with('images')->get();

To make it work, you just need to define the images relationship in the ArhitectPortfolio model:

public function images()
{
    return $this->hasMany(ArchitectPortfolioImage::class, 'architects_images_id');
}

Instead of merging we can make use of following code

$data = Architect::where("user_id", $user_id)->first();
$architect = User::find($user_id)->architect;
        $portfolio = ArchitectsPortfolio::where('architects_portfolio.architects_id', $architect->id)->paginate(6);
        foreach ($portfolio as $r) {
            $image = ArchitectsPortfolioImages::where('architects_images_id', $r->id)->first();
            if ($image) {
                $r->filename = $image->filename;
            }
        }
